Abstract

가이드 튜브와 상단부 피팅 사이의 재사용 가능한 일체식 로킹 장치는 재구성 가능한 연료 조립체의 일부분이다. 가요성 리테이너 링은 가이드 튜브 조립체의 상단부 슬리브의 부분으로서 포함된다. 리테이너 링은 상단부의 슬리브의 외주면 둘레에 제공된 홈에 수용된다. 홈에 제공된 스프링은 리테이너 링을 외축으로 바이어스 시킨다. 리케이너 링의 외부 에지는 상단부 피팅을 통해 보어재에 제공된 카운터 보어내에 수용되며, 설치된 위치에서 가이드 튜브 및 상단부 피팅을 지지하는 작용을 한다. 슬리브 또는 콜릿은 스프링에 대해 리테이너 링을 내측으로 힘을 가하도록 그리고 상단부 피팅으로 부터 가이드 튜브를 연로크하도록 카운터 보어내에 삽입 될 수 있다.The reusable integral locking device between the guide tube and the top fitting is part of the reconfigurable fuel assembly. The flexible retainer ring is included as part of the top sleeve of the guide tube assembly. The retainer ring is received in a groove provided around the outer circumferential surface of the sleeve at the upper end. A spring provided in the groove biases the retainer ring to the outer axis. The outer edge of the retainer ring is received in the counter bore provided in the bore material through the top fitting and serves to support the guide tube and the top fitting in the installed position. The sleeve or collet can be inserted into the counter bore to force the retainer ring inward against the spring and to lock the guide tube from the top fitting.
